Allow a limit to be set on the number of results in a query panel

Summary: This allows a maximum number of items to be set in a query panel.  Mostly useful when you have a query panel on the feed search and you don't want 4 billion results cluttering your dashboard.

Test Plan: Created a query panel with a maximum and it worked.  Left it blank and got the default results.

Fix weird subscribe+comment rendering

Summary:
Fixes T5146. When we're rendering a transaction group that includes a comment, we hide the "x added a comment" text, since it's implicit and obvious and cleans the UI up a little.

However, the way this works is really complicated and messy and created the T5146 issue after I made self-subscriptions have a lower priority than comments do.

Clean this code up so it makes a little more sense and gets this case right.

Don't warn about conflicts when reverting Phriction documents

Summary:
Fixes T5144. This was incorrectly checking the //content// version, not the //head// version, so reverts would raise the "conflict" warning.

Also fix a couple of FontAwesome icons.

Test Plan:
  - Edited a document.
  - Reverted a document.
  - Opened two edit tabs. Edited one, tried to edit #2, got a warning.
  - Opened two revert tabs. Reverted in one, tried to revert in #2, got a warning.
